WALLHUNG

Grant Baffle Set – WBS03

Genuine Baffle Set for Grant Vortex Wall Hung 12–21kW & 16/21kW Boilers

The Grant WBS03 Baffle Set is a genuine replacement flue baffle kit designed specifically for use with Grant Vortex Wall Hung 12–21kW and 16/21kW oil-fired condensing boilers. These baffles play a critical role in improving boiler efficiency by slowing down the flow of hot combustion gases through the heat exchanger. This allows for greater heat transfer into the central heating system, reducing fuel consumption and emissions.

Worn or missing baffles can lead to inefficient operation, excessive soot build-up, and higher fuel costs. Replacing them with the WBS03 set ensures your boiler continues to operate at optimal performance.

  Key Features & Benefits

• Enhances Boiler Efficiency
  Slows flue gas movement through the heat exchanger, maximizing heat transfer.

• Reduces Fuel Consumption & Emissions
  Improved combustion efficiency means lower heating bills and a reduced carbon footprint.

• Supports Cleaner Operation
  Minimises soot and carbon deposits in the combustion chamber and flueways.

• Robust & Heat-Resistant Construction
  Built from materials designed to withstand high combustion temperatures for long service life.

• Quick & Easy Installation
  Straightforward to fit during annual boiler servicing or routine maintenance.

 When Should You Replace the Baffle Set?

Replace your boiler baffles if:

• They show signs of warping, corrosion, or cracking

• There is excessive soot or incomplete combustion

• Your boiler is using more fuel than normal or suffering reduced heat output

• You’re completing a routine service or heat exchanger clean

Replacing faulty baffles helps maintain the designed airflow and combustion chamber dynamics, critical for system efficiency and safety.
